The result of over 12 years preparation, this is the most comprehensive English-Thai dictionary in the world. Based on the unparalleled experience of Oxford University Press in dictionary making, the translation centre at Chulalongkorn University, Bangkok has produced a dictionary which captures the idiomatic, colloquial, spoken and written character of English. Incorporating over 230,000 words and phrases, with many helpful in text boxes, a selection of useful phrases and a list of irregular verbs, it is a dynamic passport to the English language for native Thai speakers.

At the same time, it enables advanced Thai learners to develop their Thai language skills and includes a section on the characteristics of the Thai language and a list of all key government organisations.
